Commit Message

Nikita Zhandarovich April 12, 2023, 3:29 p.m. UTC 
Multiple hdmi_*_infoframe_init() functions that initialize different
types of hdmi infoframes only return default 0 value (contrary to their
descriptions). Yet these functions are still checked against possible
errors in case of failure.

This patch removes redundant checks for errors in calls to following
functions:
- hdmi_spd_infoframe_init
- hdmi_audio_infoframe_init
- hdmi_vendor_infoframe_init
- hdmi_drm_infoframe_init

Also, change their return types to void and fix descriptions.

Fixes: 2c676f378edb ("[media] hdmi: added unpack and logging functions for InfoFrames")
